Abstract

|
|
Purpose: We evaluated the structure, innervation of the extraocular pulley smooth muscle in the rabbit.
Methods: A rabbit was transcardially perfused with physiological saline followed by 4% formalin. The rabbit orbit was dissected en bloc, paraffin processed, and serially sectioned for Hematoxylin-Eosin and Masson`s trichrome stain. The distribution of the extraocular pulley smooth muscle was confirmed by immunohistochemistry with human smooth muscle(SM) α-actin.
Results: We found that the pulley structure consisted of focal condensations of eleastin and collagenous connective tissue in relationship to the rectus muscle in the equatorial Tenon`s fascia. The pulley smooth muscle in relation to medial rectus muscle was immunostained with TH and nNOS.
Conclusions: The data support the presence of the extraocular pulley smooth muscle in the rabbit orbit having both parasympathetic and sympathetic innervation. J Korean Ophthalmol Soc 48(1):142-149, 2007
